What is the benefit of sneezing in general? The easy
answer is that the thing tickling your nose might be a bad thing (like a
virus,
bacteria or pollen), and sneezing forces it out. The problem is that most
adults
sneeze mostly through their mouth, and so sneezing won’t force anything out
of
the nose. This is in contrast to most animals, who sneeze largely through
their
nose (watch your dog or cat next time). So I think that sneezing really
serves
little purpose to humans (little kids might be an exception to this).
think that sneezing is important to animals that rely heavily on the sense
of
smell, but that in us it is just an annoying 'holdover' of evolution. But
that
is just my
opinion

打喷嚏有什么用呢？由于喷嚏是因为有外来物刺激鼻腔粘膜产生的，人们马上会想
到，打喷嚏是为了把这些有害物质清除出去，同时也能清洁鼻腔，免得它被外来物堵塞
，让鼻腔更好地发挥过滤空气的作用。问题是，成年人在打喷嚏时通常是张大嘴打的，
这样的话就不容易把鼻腔里的脏物排出去，对鼻腔的清洁作用很有限。不像大多数哺乳
动物，它们是闭着嘴打喷嚏的，能有效地清洁鼻腔。多数哺乳动物的嗅觉非常敏感，它
们赖以生存，喷嚏清洁鼻腔的作用就非常重要。而人类的生存更多地靠视觉，嗅觉已大
大退化了，喷嚏的好处也就没那么明显。对人类来说，喷嚏可能只是进化的遗迹，没有
太大的益处。 | g****2
